Microphone Install the microphone at a distance of no more than 30 cm (12 inches) away from the driver's mouth, ideally on the upper right hand side of the sun visor and away from any noise source such as windscreens, window, fan/air conditioner, car stereo etc. Make sure the microphone is at a distance of at least 1.5m (4.9 ft) from the speaker and is not directed towards the speaker. Figure 15: Microphone installation. Make sure that the microphone is positioned properly (see Figure 15). Do not thread the microphone cable close to antenna cable, to avoid audio interference. Plug the microphone cable into the compatible connection in the octopus control cable. Important: Make sure that the microphone cable does not come in contact and does not interfere with the steering wheel and/or the pedals of the vehicle. Attention! The speaker and microphone (which is fitted on the sun visor above the driver) should be pointed towards opposite directions to avoid echo. RF Antenna Various RF antenna models can be installed for the Motorola in-vehicle product line. The antenna type (glass, roof mount, marine or RV antenna types) should best match the customer's application. 70 - Installation Guide
